Anna Kipp and her group in Jena, Germany, we compared the substrate specificities of human glutathione peroxidases GP1, GPX2 and GPX4 with pure enzyme systems and identical conditions
The activity of several protein kinases, and particularly of protein kinase C (PKC) sub-family members can be modulated in human neuronal cells supplemented with tocopherols and tocotrienols (Galli et al., 2017)
Furthermore, by reacting directly with -SH groups of enzymes like sedoheptulose biphosphatase, fructose biphosphatase and glyceraldehyde 3-phosphatase, H 2 O 2 inactivates these enzymes
